java - Spring @Autowired chains and regular 'new XYZ()' instantiations -

is impression correct using regular new xyz() way of instantiating component xyz prevents spring processing @autowired fields inside xyz?

second question: correct cannot use dependency injection in xyz , @ same time use final fields in xyz because of that? example:

@component public class xyz {     @autowired     private somedep dep;      private final int value;      public xyz(int value) {         this.value = value;     } } 

how make working?

so, well, accepting there no nicer way, let's way:

@component public class xyz {     @autowired     private somedep dep;      private final int value;      // factory instantiation     xyz() {         value=0;     }      private xyz(somedep dep, int value) {         this.dep = dep;         this.value = value;     }      public xyz getinstance(int value) {         return new xyz(dep, value);     } } 

??? ugly. , gets uglier when want move dependency declaration parent class....... ??? thought di nice. think have reconsider that. alternatives? missing something?

1. if create object new, @autowired won't work, because object created outside of spring ioc container. object should instantiated spring in order let inject dependencies. object (bean) container (spring application context), should initialize spring context , call context.getbean("beanname").
2. you can use constructor dependency injection here. here can read more injection types
